Letters Patent No. 73,664, dated January 21, 1868. I

IMPROVEMENT IN LAMPS.

TO ALL WHOM IT MAY CONCERN:

'Be known that I, STEPHEN SPOOR, of Phelps, in the county of Ontario, and State of New York, have invented a certain new and useful Improvement in Lamps and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specication. I

Figure 1 is a sectional elevation of my improvement.

- Figure 2,`a perspective view of the shadev detached.

Like letters of reference indicate corresponding parts in both gures.

My invention consists in a shade fitted over the cone or burner, inside the chimney, whereby the eyes are perfectly shielded, without'the use of the cumbersome arrangement usually employed, attached on the outside of the chimney.

In the drawings, A indicates the chimney, B the perforated base-plate or cap, on which the chimney .rests,-

C the wick-tube, and D the deilector or cone. These parts constitute an arrangement well known, to which I lay no claim. Over the deiector or cone is fitted a small shade, E, perferably of concave-convex form, with a central opening to prevent obstructionof' the draught above the blaze. This shade Vpreferably slides up and down within the'chimney. In that ense the shade may be operated by any suitable arrangement, but IV prefer that shown in the drawings, which consists of a cog-rack, a, attached thereto, driven by a spur-wheel, b, having a shaft projecting ont to be operated by the fingers. The cog-rack may be held to ,the spur-wheel by a spring, 0,which also acts as a stop for a nib or projection, cl, of the end of the said cog-rack to strike at the extent of the up motion. The shade thus arranged, rests over the cone, and forms a perfect shield to the eyes, while at the same time the passage of light upward, as well as downward, is unobstructed, since the shade is centrally open at the tcp. This opening allowsa free passage of the draught. When'entirely downtheI shade simply rests on top of the deflectcr or'cone, and produces n o shade at all, So it will beseen that the device may be used as a shade or not, at pleasure.

This shade is as eiective in shielding the eyes as the ordinary large shade fitted outside the chimney. I- avoid all such cumbersome and awkward attachments, 'and substitute one inside that is always in place, which is not liable to disarrangement or obstruction, and which is of the simplest and most 'effective character.

' What I claim as my invention, and desire to secure by Letters Patent, is

A shade, E, within the chimney A, arranged and operating substantially as and for the purposes herein set forth.. V p

In witness whereof, I have herenntosigned my name in the presence of two subscribing witnesses.
